'Cloud' in the Bible

And while he said these things, the shade of a cloud came over them, and they were full of fear when they went into the cloud.

And there was a voice from the cloud saying, This is my Son, the man of my selection; give ear to him.

Then he said to the people, When you see a cloud coming up in the west, straight away you say, There will be rain; and so it is.

And then they will see the Son of man coming in a cloud, with power and great glory.
